“We were not under a lot of pressure. We did not work weekends nor late at night and took our coffee breaks.”
None-the-less, they were successful in seeing the first absorption of energy between the two levels of the spin of ½ magnitude which are split in the presence of a magnetic field—the Zeeman Effect.
Two dimensional Nuclear Magnetic Resonance (2D-NMR) quickly followed from the remarkable theoretical musings of Jean Jeener: ideas that were experimentally developed by Richard Ernst and others, and taken to new levels of sensitivity and resolution with the ability to study structure, function and kinetics. This moved NMR from chemistry to biochemistry, into the life sciences and, finally, with the founding work of Raymond Andrews, Paul Lauterbur, and Sir Peter Mansfield culminated in the development of non-invasive Magnetic Resonance Imaging (MRI) (with the word “Nuclear” removed to placate the masses).
